"Sudan's Ministry of Foreign Affairs expresses its strong condemnation of the terrorist blast which targeted the tax office in the Turkish capital Ankara and caused great damage to the building," the ministry said in a statement.

The bombing is "a crime contradicting all humanitarian values and principles," it added.

The ministry also highlighted "Sudan's full solidarity with the government of Turkey in facing criminal acts," and called for the international community to intensify efforts and cooperation against all forms of terrorist acts.

The Turkish authorities said on Thursday that the explosion at the tax office in Ankara was caused by a bomb and the suspected bomber was killed by police.
